 | 2 |  | 
 | 3 | - 0.3 - Created based off of scanner & INSTALL from the original touchscreen | 
 | 4 |   driver on freshmeat (http://freshmeat.net/projects/3mtouchscreendriver) | 
 | 5 | - Amended for linux-2.4.18, then 2.4.19 | 
 | 6 |  | 
 | 7 | - 0.5 - Complete rewrite using Linux Input in 2.6.3 | 
 | 8 |    Unfortunately no calibration support at this time | 
 | 9 |  | 
 | 10 | - 1.4 - Multiple changes to support the EXII 5000UC and house cleaning | 
 | 11 |    Changed reset from standard USB dev reset to vendor reset | 
 | 12 |    Changed data sent to host from compensated to raw coordinates | 
 | 13 |    Eliminated vendor/product module params | 
 | 14 |    Performed multiple successfull tests with an EXII-5010UC | 
 | 15 |  | 
 | 16 | SUPPORTED HARDWARE: |

 | 32 | DRIVER NOTES: | 
 | 33 |  | 
 | 34 | Installation is simple, you only need to add Linux Input, Linux USB, and the  | 
 | 35 | driver to the kernel.  The driver can also be optionally built as a module. | 
 | 36 |  | 
 | 37 | This driver appears to be one of possible 2 Linux USB Input Touchscreen | 
 | 38 | drivers.  Although 3M produces a binary only driver available for | 
 | 39 | download, I persist in updating this driver since I would like to use the | 
 | 40 | touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the | 
 | 41 | logical choice is to use Linux Imput. | 
 | 42 |  | 
 | 43 | Currently there is no way to calibrate the device via this driver.  Even if | 
 | 44 | the device could be calibrated, the driver pulls to raw coordinate data from | 
 | 45 | the controller.  This means calibration must be performed within the | 
 | 46 | userspace. | 
 | 47 |  | 
 | 48 | The controller screen resolution is now 0 to 16384 for both X and Y reporting | 
 | 49 | the raw touch data.  This is the same for the old and new capacitive USB | 
 | 50 | controllers. | 
 | 51 |  | 
 | 52 | Perhaps at some point an abstract function will be placed into evdev so  | 
 | 53 | generic functions like calibrations, resets, and vendor information can be  | 
 | 54 | requested from the userspace (And the drivers would handle the vendor specific | 
 | 55 | tasks). |

 | 60 |  | 
 | 61 | TODO: | 
 | 62 |  | 
 | 63 | Implement a control urb again to handle requests to and from the device | 
 | 64 | such as calibration, etc once/if it becomes available. | 
 | 65 |  | 
 | 66 | DISCLAMER: | 
 | 67 |  | 
 | 68 | I am not a MicroTouch/3M employee, nor have I ever been.  3M does not support  | 
 | 69 | this driver!  If you want touch drivers only supported within X, please go to: |

 | 73 | THANKS: | 
 | 74 |  | 
 | 75 | A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for | 
 | 76 | testing! |
